Both drivers were killed in the crash last Tuesday morning on I-80/35 at Morningstar Drive. The Iowa State Patrol reported a Mini Cooper was traveling east in the westbound lanes just before 1 a.m. when it crashed head-on into a Ford Taurus.

The Mini Cooper's driver, Brandon Anderson, 25, of Des Moines, and Kevin O'Sullivan, 53, of Elizabeth, Illinois, died in the crash.

State Patrol investigators said tests show Anderson's blood alcohol content was .304, which is four times the legal limit.

Investigators also said Anderson was driving in excess of 100 mph. The speedometer has been sent off to a lab to get the exact speed reading at the time of the crash.

Investigators said they believe both cars were traveling at full interstate speed when they collided head-on.

Two other drivers were able to swerve out of the way to avoid the crash.
